Struct VmLibrary 

pub struct VmLibrary {
    pub source: Library,
    pub modules: Modules,
    /* private fields */
}

Where CALL finds a program on the VM (load-module.md §8.2): among the programs already read, those of the run’s first source or module first; then NAME.iwm in the program libraries; then source there, lowered as CALL loads it.

Fields

source: Library

modules: Modules

Implementations

impl VmLibrary

pub fn new(source: Library) -> Self

The library’s directories are where NAME.iwm is looked for, in their order.

pub fn for_module(source: Library, path: &Path, module: LoadedModule) -> Self

A library for a run that begins with module, read from path, whose programs come before any other’s.

Trait Implementations

impl Loader<Rc<Code>> for VmLibrary

fn mapset(&mut self, name: &str) -> Option<Result<Mapset, String>>

A mapset a module already read holds, else one from the copy libraries.

fn program(&mut self, name: &str) -> Result<LoadedProgram<Rc<Code>>, LoadError>

The program whose PROGRAM-ID CALL names, compiled.

fn holder(&self, entry: &str) -> Option<String>

The PROGRAM-ID of a program not yet loaded that has an ENTRY of this name.

fn entry(program: &Rc<Code>, name: &str) -> Option<usize>

Which of a loaded program’s ENTRY statements has this name.

fn shape(program: &Rc<Code>) -> (usize, usize)

A loaded program’s file count and storage size.

fn nested(program: &Rc<Code>) -> &[String]

The PROGRAM-IDs of the programs a loaded program contains, which a CANCEL of it reaches.

fn source(program: &Rc<Code>, file: usize) -> Option<String>

Source file file of a loaded program’s source table, by name.

fn class( &mut self, external: &str, ) -> Result<Option<FoundClass<Rc<ClassCode<Rc<Code>>>>>, String>

The COBOL class definition of this external name, its data and methods each a program the executor runs; None for a Java class.
